Making the hair collide with another object
To have hair interact with a surface, you must set the hair to collide with the
surface. A collision object can be a NURBS or polygonal surface. In the next
part of the lesson you set the curtain to collide with the sphere and then play
the simulation.
To enhance the curtain for collisions
1 To select the hair system, drag around the hair curves and then select
Hair > Convert Selection > To Hair Systems.
2 In the hairSystemShape1 tab of the Attribute Editor, set the hair system
attributes as follows:
In the Clump and Hair Shape section, set Clump Width to 0.
In the Dynamics section, set Stiffness to 0.
To make the hair collide with the sphere
1 Select the hair system and the sphere (drag around the hair curves and
sphere).
2 Select Hair > Make Collide.
3 Play the simulation.
Now the sphere collides with the curtain, pushing the strands of hair
aside as it passes through.
Assigning a Paint Effects brush to the hair
You can assign a Paint Effects brush to a hair system to achieve a variety of
effects. In these next steps you apply the red beads brush to the hair system
to create the beaded curtain. Then you modify the brush and hair system
settings to achieve the desired look.
To turn the hair curtain into a beaded curtain
1 To select the hair system, drag around the hair curves and select Hair >
Convert Selection > To Hair Systems.
2 Open the Visor (Window > General Editors > Visor).
3 Go to the glass folder and select the beadsRed.mel brush.
